DOI: 10.1038/s41550-020-01276-x
Abstract: Fast radio bursts (FRBs) are short (millisecond) radio pulses originating from enigmatic sources at extragalactic distances so far lacking a detection in other energy bands. Magnetized neutron stars (magnetars) have been considered as the sources… read more here.

DOI: 10.1088/1674-4527/acdabe
Abstract: The detection of quasi-periodic oscillations (QPOs) in magnetar giant flares (GFs) has brought a new perspective to study the mechanism of magnetar bursts. Due to the scarcity of GFs, searching QPOs from magnetar short bursts… read more here.

DOI: 10.1093/mnras/stac446
Abstract: We report on the the long term monitoring campaign of the seemingly youngest magnetar Swift J1818.0-1607 at radio and X-ray wavelengths over a span of one year. We obtained a coherent timing solution for the magnetar… read more here.

Tidal capture of an asteroid by a magnetar: FRB-like bursts, glitch and anti-glitch

DOI: 10.1093/mnras/stad1585
Abstract: Recently, remarkable anti-glitch and glitch accompanied by bright radio bursts of the Galactic magnetar SGR J1935+2154 were discovered. These two infrequent temporal coincidences between the glitch/anti-glitch and the fast radio burst (FRB)-like bursts reveal their… read more here.

DOI: 10.1093/mnras/stx2095
Abstract: We examine millisecond magnetars as central engines of Gamma Ray Bursts' (GRB) prompt emission. Using the proto-magnetar wind model of Metzger et al. 2011, we estimate the temporal evolution of the magnetization and power injection… read more here.

DOI: 10.1103/physrevd.100.123014
Abstract: Two accretion columns have been argued to form over the surface of a newborn millisecond magnetar for an extremely high accretion rate $\gtrsim1.8\times10^{-2}M_\odot\ {\rm s^{-1}}$ that may occur in the core-collapse of a massive star.… read more here.
